splicing electric wires

[ldj]

Years ago they used something I think called nurley nut or knurly nut. I'm wanting to splice some wire and my friend Google doesn't know about them. Maybe I have the wrong name. I think made of copper and the bolt was split and the nut pushed down clamping wires together.

Try kearney split bolts

 

[gmccool]

I always called them split bolts

 

[joeysmith]

These are what most use now
Polaris connector

Yes that is it. Wonder why Google didn't list them as a way to splice wire? Thanks Leo

We called them, wire-nuts.
Or, scotch locks, they were made by 3-M.

Lots of ways to splice wire, but the terms really depend on wire size. Split bolts are usually used bigger sizes, wire-nuts up to about 8ga. Maybe even 10.

Specialty items like the Polaris above for big stuff and Wago for little stuff are also available and don't require any extra tape steps.

With respect, Scotch Locks are applied to stranded wire with a squeeze of a metal strip into and through the insulation. They promote corrosion, may damage the conductors, come loose, and I do not recommend them at all. I have repaired more systems that were "fixed" with these gizmoes" than I can count. Jim

How many trailer lights have been wired that way? How many of those have intermittent light problems? Same answer.

I hate those things.

I think they come from the factory corroded. I hate those things.

I have two bags of 500 each that were on a shelf I bought at an auction. I have used maybe a dozen of them over the past ten years, mostly for temporary emergency repairs. Most of those worked until I replaced the whole wire. Some of them were more trouble than they were worth.

Application ?

OK, so the Polaris connector is for 120v wiring connections from what I see of the listings of them. Wire nuts also for 120v wiring. Scotchlocks are generally for 12v automotive use. Any other wiring connections?

It's funny you brought this up, as that was the recent diagnosis on my train layout. The suitcase connectors that feed the tracks from the buss were not conducting as they should & had to be re-crimped in spots. It explained why some of my engines were acting possessed. They rely on signals to the circuit board from the command station, as well as the juice to run them. If those signals come in crossed, data packets eroded, etc, bad things happen. Or nothing happens. So far I have three engines with boards that will light up, but not respond. Even to a master reset. Will most likely have to pitch those & get new ones.

Edit: I'll be soldering all those crummy connections in the mean time.

I'm a retired I.B.E.W. electrician, for more than 20 years.
The wire nuts that were used back then do not look like the ones I see on line today.
